Transparent Single‐Dye NIR Photonic Platform for Multimodal Optical Authentication
Advanced Optical Materials, EarlyView.A single‐component DHP‐SQ dye integrates visible transparency, near‐infrared (NIR) fluorescence, and photothermal functionality into one molecular platform. NIR‐selective visualization transforms visually imperceptible printed patterns into readily authenticated information, while screen‐printing compatibility enables well‐defined patterning on diverse

Rigid Boron‐Fused Frameworks for Efficient Near‐Infrared Emission and Optical Gain Beyond 900 nm
Advanced Optical Materials, EarlyView.Multiple‐resonance (MR)‐derived boron‐fused frameworks were integrated into narrow‐gap, long‐range charge‐transfer emitters to reduce structural relaxation and electron‐vibrational coupling. This strategy significantly decreases nonradiative losses, leading to improved near‐infrared (NIR) luminescence efficiency and low‐threshold amplified spontaneous ...

Single‐Photon Emitters in Thickness‐Controlled hBN Directly Grown on Silicon Platform
Advanced Optical Materials, EarlyView.Direct, catalyst‐free CVD growth produces thickness‐controlled hBN films on SiO2/Si without transfer. Growth temperature, film thickness, and carbon incorporation tune the density and single‐photon fraction of defect emitters while preserving the hBN lattice structure.
